Embodiment 1

[0030] Example 1: Spinning recycled cotton / polyester filament under-supporting smooth composite yarn

[0031] Using the under-supporting composite spinning device for filament spiral expansion of the present invention, the polyester filament bundle is spread according to the above yarn spreading method, and then twisted with recycled cotton fiber strands at the nip of the front roller Composite to form a smooth composite yarn, the specific process parameters are shown in the table below. The spun polyester filaments are wrapped and wrapped with recycled noil short fiber strands. The yarn hairiness index, twist angle, breaking strength, elongation at break and yarn fineness irregularity listed in the table below. Among them, the spinning rate is very high, which means that there is very little loss of fiber such as flying flowers, shavings, and broken ends; Low, indicating good spinnability and high processing efficiency in yarn forming. During the spinning process, there is...

Abstract

The invention relates to a lower support type composite spinning mechanism for spirally spreading a filament, a process adopting the mechanism and application thereof. The mechanism is composed of a yarn guider and a screw-thread yarn spreading device. The technological steps are as follows: downwards guiding the filament through the yarn guider and guiding the filament into the threaded yarn spreading device located below a short fiber whisker strip; enabling the fed filament to spread uniformly along the screw thread by following the rotation of the screw-thread yarn spreading device to form a lower support filament mesh due to the guiding function of a screw thread and feeding the filament and the short fiber whisker strip passing above into a front roller synchronously; and wrapping the short fiber whisker strip on the lower filament mesh under the action of twisting to form a composite yarn. The mechanism is light, practical, and convenient to install and adjust, can improve fiber spinning efficiency and high count of the fibers efficiently, reduce flying, dropped chips and fluff in spinning and is suitable for composite spinning of high count soft and smooth yarns of shorter, weaker and ultra-short fibers.

Description

technical field [0001] The invention relates to a filament unfolding and protection type composite spinning device, a spinning method using the device and an application of the device. Background technique [0002] Composite yarns are divided into staple fiber composite yarns, filament composite yarns and staple / filament composite yarns, among which staple / filament composite yarns are further divided into core-spun yarns, wrapping yarns, ply yarns, etc. The production methods of short fiber / filament composite yarn include ring spinning, air-jet spinning, electrospinning, hollow spindle spinning, rotor spinning, etc., and ring spinning is the most widely used. There are two ways to feed the filament yarn, one is that the filament yarn is directly fed into the twisting area of ​​the staple fiber, and then directly wound and twisted with the staple fiber; the other is that the filament yarn is short under high tension. The fibers are wound onto a filament yarn to form a coresp...
